Embodiment
Fig. 1 shows one and is used to be connected to a sensor module 10 on the electric conductor 5.More specifically, described sensor module 10 is connected on the insulator 7 of described electric conductor 5.With reference to figure 2, sensor module 10 comprises a pedestal 20 and a pair of detector housing 30 that extends out from described pedestal 20 again.Each described detector housing 30 has a cavity 32 that is used to hold the magnetic field detector (not shown).An embodiment of described magnetic field detector is a Hall element.For the person of ordinary skill of the art, this is apparently, be that one or two detector housing 30 can be directly connected on the described pedestal 20 or by an intermediary element (not shown) and is connected on the described pedestal 20, described intermediary element is placed between described pedestal 20 and one of them the described detector housing 30.As what seen in Fig. 2, described detector housing 30 directly extends out from described pedestal 20.On the contrary, Fig. 1 shows in the described pair of detectors shell 30, and wherein said detector housing 30 is connected on the element 50 that selectively extends, and described element 50 extends out from described pedestal 20.Described extensible element 50 and described pedestal 20 match to regulate the distance between the described pair of detectors shell 30.
Again with reference to figure 3, it shows pair of detectors shell 30 now, and described detector housing 30 extends out and nestles up an electric conductor 5 from a pedestal 20.In order to help that described assembly 10 is connected on the described electric conductor 5, a pair of anchor clamps 60 that are used for additional support are provided.Described detector housing 30 is spaced laterally apart each other and is substantially parallel to each other is important.
With reference now to Fig. 4,, it shows and is installed in an assembly 10 on the bus-bar 8.The described element 50 that selectively extends is installed on the various electric conductors described assembly 10.In Fig. 4, but the ratch element 57 that a pair of elastic deflection is provided to regulate the distance between the described pair of detectors shell 30, wherein said ratch element 57 has one group of tooth 58.But described extensible element 50 is adjusted by the ratch element 57 of the described elastic deflection of inside extruding, make described extensible element 50 can near and move away from described pedestal 20, but the ratch element 57 of wherein said elastic deflection can shift out in described one group of tooth 58 one or more a plurality of tooth from a contact position on the described pedestal 20.Those of ordinary skill in the art recognizes horse back, in order can to locate described detector housing 30 and described element 10 to be installed on the conductor fixed to one anotherly, but only need provide the ratch element 57 of an elastic deflection.
With reference now to Fig. 5,, it shows the exploded view of a sensor module 10, and described exploded view suitably shows the described pedestal 20 of placing a cavity 22 therein.An electronic circuit board 70 is placed on described cavity 22 inside.A lid 28 that connects described pedestal 20 is provided, in the time of with the thing in the described lid 28 approaching described cavitys 22 of box lunch, prevents that dust, water and other external element from entering base cavity 22.Provide one to be used for determining signaling bearer element (not shown), for example lead or optical cable, cable channel 55 from a magnetic field detector of described cavity 32 inside that are placed on described detector housing 30 to the route the described electronic circuit board 70, wherein said cable channel 55 extends out from the described element 50 that selectively extends.Described signaling bearer element is connected on the described electronic circuit board 70 effectively.Described cable channel 55 when described extensible element 50 near and move so that adapt to various conductor size away from described pedestal 20, during for example described bus-bar 8, prevent that described signaling bearer element tangles.Described electronic circuit board 70 can comprise logical circuit, and described logical circuit is used to handle the described signal from described pair of magnetic field detecting device, and its output provides by pin connector 80.
